Cross R UNITED i-STATES v To all whom, it may concern:

Be it 'known that I, FREDERIC NEPHEAUK BOXER, civil engineer, a citizenof Canada," residing in the city of Montreal, Province of Quebec,Canada,have inventedanew and usef ul Composition of Matter to be Usedfor Bendering Water-Proof and Uninfiammable all Substances to which itis Applied, of which the following is aspecification. I

My composition consists of the following ingredients, mixed in theproportions below given, but varying slightly, according to the strengthof the silicate used, and vWhether it I contains alkali or is neutral,viz: silicate of soda soluble glass} (it 30 Baum onega on; I pure wa erone gal on; Wllltlll", ashes and 'pulverizeil soapstone, fifmunds;Indiar%h egone poun )arafiine, one-half pound. he above ingredIen'Ts arethoroughly mixed together until they form a fine plastic adhesivecement, which hardens quickly, and can be used for cementing togethersheets of paper, straw-board, tarred or resined roofing paper or felt,and anyother substances to which it will adhere. The same composition,in a more diluted state, can be used to form colored cements, and,withthe addition of a-small percentage of lime, forms a permanent wash forrendering nmnflammable shingle roofs and wood-work.

In mixing the foregoing ingredients I prefer to dilute the fluidsilicate with a portion of the required quantity .of water specified andapply the balance to moistening the whiting before thoroughlyamalgamatingdhem, and then add the rubber and parafline reduced toliquid form.

eierence PATENT OFFIc FREDERIC N EPHEAU BOXER, OF MONTREAL, QUEBEC,CANADA.

SPECIFICATION forming part of Letters Patent No. 430,766, June 24, 1890.

Application filed December 26, 1889- Serial No. 334,980- (No specimens.)

fore their slight inflammability is counteracted by the silicate andwhiting, and their use in the composition is to render it more plasticand water-proof.

My invention is intended to apply more particularly to the followingpurposes, although there are many other uses to which it could beemployed: first, to render common tarred or resined roofing-paper or.other inflammable materials flame-proof by cemen ting them together orby coating themv over with the before-described composition; second, forcementing together two or more plies of paper, felt, or straw-board tobe used as a substitute for wood or plaster in the interior or on theexterior of buildings; third, as a .Wash for shiugled roofs andwood-work generally; fourth, as a deafening substance under floors whenincorporated .with sawdust; fifth, asaplaslic cement combined withsoapstone; ,7 1

I am aware that silicate has bee 1 sed before for different purposes;butl am not aware that thesam e ingredients which compose my compositionof matter have been used for the purposes herein described.

W'hat I desire to secure by Letters Patent 65 in the United States is-The herein-described composition of matter, consisting of soluble glasscombined with whiting, ashes, and pulverized soapstone, in-

described proportions, as and for the purposes set forth.
